Application filed August 30, 1912.

To all whom it may concern Be it known that I, ALEXANDER BEATON WALKER, a subject of the King of Great Britain and Ireland, residing at VVallsend, in the county of Northumberland, England, have invented new and useful Improvements in or Relating to Burners for Gas and Similar Radiators, Stoves, and the like, of which the following is a specification.

This invention relates to burners for gas and similar radiators, stoves and the like.

The invention has special reference to burners for those types of gas radiators or stoves wherein are usually employed Argand or atmospheric burners fitted with glass chimneys and wherein the products of combustion pass or circulate through a passage or passages in the casing of the radiator or stove before dispersing intothe atmosphere, and the invention has for its object to increase the heating efliciency of such radiators or stoves.

According to this invention Iemploy one or more bunsen or other suitable high temperature gas burners and with each burner I combine a chimney, casing, funnel or the like made of silica, steatite or other suitable refractory material and a heat radiating medium also made of silica, steatite or other suitable refractory material. The radiating medium may be in the form of a spiral or other suitable coil, though if desired, it may be of any other suitable form. The burner may be of any suitable type but it is preferably of the type which gives an annular flame. The coil may be parallel throughout its length or cone-shaped or tapered, but is preferably more or less of the shape of two cones arranged with their apices pointing toward each other. In every case however, the lower portion of the radiating medium is preferably shaped to follow or conform to the shape of the flame of the burner.

According to one way of carrying the invention into practice I employ a Bunsen burner which gives an annular flame and fit the burner with a chimney of suitable length made of fused or vitreous silica. Within the chimney and supported on or from the burner or otherwise in any suitable manner I arrange a spiral coil also made of fused or vitreous silica and more or less of the shape of two cones arranged in alinement with their apices abutting.

In use there is in the coil next to the burner a zone of very high temperature in Specification of Letters Patent.

which practically perfect combustion takes place, and the chimney and coil radiate a large amount of heat, and a Bunsen burner fitted as described is considerably more efficient than an ordinary Bunsen burner or an Argand or atmospheric burner. Further the chimney and coil are practically indestructible by the heat of the burner.

In the accompanying drawings, Figure l is a central vertical section illustrating the preferred manner of carrying the invention into practice, and Fig. 2 is a similar view of a modification.

Referring to the drawings, a is a Bunsen burner of the kind giving an annular flame and fitted with a cylindrical chimney, casing or funnel b of fused or vitreous silica. The radiating element is fitted within the chimney, casing or funnel b, and is preferably formed of two parts, viz., a lower tapered spiral or helix 0 of fused or vitreous silica so shaped as to conform as nearly as possible to the contour of the flame of the burner a, and an upper oppositely disposed or inverted conical or tapered spiral or helix cl also of fused or vitreous silica. attached to or forming a continuation of the lower spiral or helix 0 and provided to act as a regenerator to utilize the heat of the products of combustion and convert it into radiant heat. The inverted spiral or helix (Z is the form preferred, since it is found by experiment that it gives the best combination of regeneration and effective radiation since it insures that the heat is chiefly concentrated on the outside of the coils where it is most effective for the purpose of radiation. The form of the spiral or helical elements provides a relatively large radiating surface with a comparatively small mass so that a high temperature is obtained. It also has the advantage of giving the freest possible passage to the flame and the combustion products and thus insures complete combustion and consequent absence of smell.

The lower spiral or helix 0 may rest on protuberances e on the inner surface of the chimney, casing or funnel b, and the upper spiral or helix (Z may be supported on the lower spiral or helix, the upper spiral or helix being provided with an extension f which projects through an eve g at the apex of the spiral or helix 0 and keeps the latter perpendicular.

It will be evident that the form of the radiating and regenerative elements may be to some extent varied Without departing from the nature of the invention, 6. g. the double cone arrangement might, as shown in Fig. 2, be formed of fused or vitreous silica bent zigzag so as to form a double coneshaped skeleton of vertical members constricted or bent inwardly so as to form a Waist at about the center of their length. The conical regenerative element cl may be further provided With inwardly extending portions or projections to assist in trapping the heat of the products of combustion provided that such portions or projections are not suificient to unduly impede the flow of the gases.

W hat I claim and desire to secure by Letters Patent is r 1. The combination of a burner of the Bunsen type, a chimney of highly refractory material surrounding the burner, a

cheat radiating element of highly refractory material, such as silica, shaped as a hollow skeleton to follow the contour of and present a requisite conducting and radiating surface to the flame, and a regenerative element of similar material twisted spirally.

2. The combination of a burner of the Bunsen type, a chimney of highly refractory material surrounding the burner, a heat radiating element and a regenerative element of highly refractory material shaped as a double cone spiral. r

3. In gas burners and radiators the combination of a vertical burner, a chimney of highly refractory material mounted over the burner, a heat radiating-element of highly refractory material disposed Within the chimney and extending longitudinally thereof for the greater part of the length of the chimney, said radiating element at its extremitiesextending to the Wall of the chimney and contracting to a Waist between its extremities.

4. In gas burners and radiators the combination of a vertical burner, a chimney of highly refractory material mounted over the burner, a radiating element of highly refractory material disposed \vithinthe chimney and extending longitudinally thereof for the greater part of the length of the chimney, said radiating element at its ex-r tremities extending to the wall of the chimney and contracting to a Waist between its extremities.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
